Hidrodinâmica e transferência de oxigênio em três biorreatores Airlift de circulação interna geometricamente semelhantes
(Universidade Federal de São Carlos, 2009-03-12)
Internal-loop airlift reactors (ALR) are a special class of pneumatic reactors. The use of this type of reactor has been attractive for chemical and biological reactions because of their simple construction without moving ...
Modelo matemático do processo de purificação do ácido clavulânico por troca iônica em coluna de leito fixo
(Universidade Federal de São Carlos, 2009-08-04)
Clavulanic acid (CA) is a β-lactam antibiotic produced industrially by submerged cultures of the filamentous bacterium Streptomyces clavuligerus. Due to its importance, several studies on the purification of clavulanic ...
Catalisadores de Pt suportados, obtidos pelo método solgel : efeito do cério na atividade e estabilidade nas reações de reforma do metano
(Universidade Federal de São Carlos, 2009-12-11)
The effect of Ce as a structural and electronic promoter on the activity and stability of Pt catalysts supported on Al2O3 for methane reforming reactions were investigated to elucidate the metal-support interaction. Pt/Al2O3 ...
Investigação do efeito de injeção de líquido por orifícios múltiplos na formação de gotas em um lavador Venturi
(Universidade Federal de São Carlos, 2009-02-20)
Venturi scrubbers are widely used in industrial plants in the cleaning of gases. In these scrubbers, the cleaning elements are the droplets formed at the injection of a liquid in the gas
containing pollutants. The droplets ...
Análise da secagem de pastas em leito de jorro
(Universidade Federal de São Carlos, 2009-03-09)
The objective of this Doctoral Thesis was to analyse the fluidynamics and the heat and mass transfer of paste drying in a spouted bed under transient operation and to obtain
detailed experimental data on the disturbed ...
Características temporais da concentração de material particulado na atmosfera da cidade de São Carlos - SP
(Universidade Federal de São Carlos, 2009-03-19)
The city of São Carlos, of medium size of São Paulo State, can be considered as representative of the Brazilian Southeast area, with agricultural activities practically equivalent to the industrial ones. As part of that ...
Fluidodinâmica de leitos fluidizados e vibrofluidizados operando com partículas planas
(Universidade Federal de São Carlos, 2009-03-12)
The use of fluidized beds as a unit operation for drying of particulate materials is common in industrial processes. However, most works published in the literature, focus the drying of uniform particles, in a narrow range ...
Simulação da perda de carga e da eficiência de coleta em ciclones através da fluidodinâmica computacional (CFD)
(Universidade Federal de São Carlos, 2009-08-05)
El objetivo del presente trabajo fue simular la descarga de un flujo compuesto por fases gaseosa y solida dentro de un equipo denominado ciclón mediante la técnica numérica denominada Fluido dinámica computacional (CFD). ...
Catalisadores contendo espécies V2O5 ou VO2+ : atividade e seletividade na redução de NO com amônia
(Universidade Federal de São Carlos, 2009-08-03)
The selective catalytic reduction of NOx with ammonia is the best technology available today to carry out the abatement of nitrogen oxide emissions in industrial gas effluents. Currently, vanadia-titania catalysts promoted ...
Transformação de cicloexano e metilcicloexano sobre as zeólitas HMCM-22, HZSM-5 e HUSY rendimento e seletividade a hidrocarbonetos leves
(Universidade Federal de São Carlos, 2009-03-27)
In Brazil, the oil production with high naphthenic hydrocarbon (HC) content and the hard growing for the petrochemical market have led to the necessity to maximize the production of light HC (in special light olefins). The ...
